[Rendering qualified medical services to patients with fractures of long tubular bones].

The conditions for rendering aid to and treatment of the injured in extreme situations require insistantly the development of new methods for skilled medical service. From analysis of treatment of 114 patients with fractures of the long tubular bones the authors conclude that the use of various types of pin apparatuses for this purpose is expedient because they possess advantages over the nail apparatuses. Analysis of treatment of 90 patients showed the expediency of using some auxiliary devices for immobilization of peripheral erimetaphyseal fractures and oblique and spiral diaphyseal fractures.

[Endoprosthesis of the elbow joint in sequelae of gunshot wounds].

5 patients have been implanted the endoprostheses of Sivash K. M. to restore functions of the upper limb after the gunshot injury in the area of elbow joint with the clinico-roentgenologic bone defect detection. Coarse cicatricial changes in the area of an articulation with presence of foreign bodies are characteristic for those patients. There have been achieved significant improvement of restoration of active movement of elbow joint and upper limb in whole with 4 of them in spite of high danger of possible post-operative inflammation. In one case due to hard physical labour there have been noted break of an endoprosthesis with the subsequent inflammation. The endoprosthesis has been removed. The most stable positive outcomes proved by physiological tests of the neuromuscular system of upper limbs are observed at endoprosthetics of elbow joint with replacement of the soft tissue defect with completely vascularized musculocutaneous autotransplant.

[Correction of extensive defects of long bones by using bi- and multifocal distraction-compression osteosynthesis].

Replacement of extensive defects in long bones on the basis of one or more osteotomies is analysed. The authors substantiate the principles and the new methods of +multifocal distraction-compression osteosynthesis which allow healing of the fracture to be combined with accelerated replacement of the bone defect. The errors, complications, and the results of treatment of 104 patients are discussed to evaluate the efficacy of the applied methods and confirm the drawn conclusions. Particular attention is paid to the significance of a complex of optimal mechanical and biological factors in the formation of the regenerative tissue in accelerated replacement of the bone defects on the basis of several osteotomies. It is shown that the advantage of the new variants of the methods of replacement of long tubular bones on the basis of several osteotomies consists in combination of the healing of open fractures with accelerated restoration of the length of the extremity.

[Computer-assisted differential diagnosis of cerebral stroke].

An automatic system of the stage-by-stage differential diagnosis of acute disorders of the cerebral circulation has been developed. Investigation of the efficacy of computer-aided diagnosis and its comparison to the diagnosis made by physicians at different levels of the care of patients with acute impairments of the cerebral circulation have shown the advisability of employing this system in the diagnosis of brain stroke at the prehospital stage at variable levels of the public health service.

[Models of biological membranes containing gangliosides].

Molecular and supermolecular peculiarities in multicomponent liotropic systems ganglioside-water, ganglioside-cerebroside-water, ganglioside-lecithin-water, ganglioside-lecithin-troponin-tropomyosin-water were studied by polarizing microscopy and rentgenography. The results obtained by these two methods are in good agreement. Mesomorphism and phase changes depending on the concentrations of components and compounds of systems were established.
